Following the Flashback malware scare this spring, Apple is stepping up its focus on security and malware protection in Mountain Lion. The release notes for the latest Mountain Lion developer preview include references to a “new Mountain Lion Security Updates system” that checks for security updates on a daily basis, uses a more secure connection when communicating with Apple’s update servers, and can install required updates automatically when a Mac is restarted.
Based on the release notes for the system, Apple is making the security update process automatic and has designed it to runs as a system process rather than a user task. Presumably that means it will function without a user logged in or while non-admin users are logged in. All in all, that’s similar to Microsoft’s Windows update feature and a good thing for users.
That doesn’t mean that this setup will be great fit for businesses, schools, and other organizations with large Mac populations.
